1,Python语法层面对面向切面编程的支持(方法名装饰后改变为log)
__author__ = 'Administrator' import time def log(func):
def wrapper(*args):
start = time.time()
func(args)
end =time.time()
print 'func used time is :', end - start
return wrapper @log
def reg(args): print 'welcome %s ' %(args[0]) reg('joeyon','123456')
2,functools模块对面向切面的支持(方法名装饰后不改变)
import time
from functools import wraps def log(func):
@wraps(func)
def wrapper(arg1,arg2):
start = time.time()
func(arg1,arg2)
end =time.time()
print 'func used time is :', end - start
return wrapper @log
def reg(username,pwd): print 'welcome %s ' %(username) reg('joeyon','123456')
